Frequently Asked Questions


How many pages can I expect to get out of these cartridges?

The Brother LC51BK Black Compatible Ink Cartridge is good for up to 500 pages, while the Brother LC51 color cartridges are good for up to 400 pages. Because we sell them as twin packs, you’re actually getting 1000 pages for black inks, and 800 pages for color inks! These yields depend on printer usage frequency, printer settings, and paper type.


Why shouldn’t I just buy original cartridges instead of your remanufactured cartridges?

Carrot Ink remanufactured cartridges are just as good, if not better than name-brand inks and cost way less. You’ll save money without sacrificing quality.


Do you offer free shipping?

Yes! Just purchase $40 or more worth of our products, and you can take advantage of this great offer.  If, however, you live outside the 48 contiguous states, shipping costs $24.95.
